SUPPORT FOR NON-CONDUCTING COVERINGS.

SPECIFICATION forming part of Letters Patent No. 494,312, dated March28, 1893.

Application filed September 22, 1892. Serial No. 446.524. No model.)

This invention relates to certain new and useful improvements inremovable or detach-' able supports for the non-conducting coverings ofheating tanks or vessels; and it con sists substantially in suchfeatures of arrangement, construction, and combinations of parts as willhereinafter be more particularly described and claimed.

The object of the invention is to providea simple and secure support bywhich non-con-; ducting coverings of felt or canvas employed uponheating tanks or vessels will be securely and perfectly maintained inposition, a fur ther object of "the invention being to enable. suchnon-conducting covering to be quickly; placed into position or applied;and also to en-- able the covering to be removed very quickly either inwhole or in part.

The invention is intended more particularly for use in'connection withnon-conducting coverings employed upon large heating vessels or tanksusually constructed of a number of superimposed sections which areunited together by flanges; instances of the kind of heating vessel ortank intendedbeing vacuum pans, evaporating pans, &c., used in sugarrefineries, distilleries, and such like places.

In the accompanying drawings I have illustrated my invention as appliedto a vacuum pan, and in these drawings Figure 1 represents an elevationof a vacuum pan when covered by a non-conducting covering, the parts ofwhich covering that join being shown as fastened together by a stronglacing usually termed bonnet lacing. Fig. 2 is a view illustrating onesection of the vacuum pan, and showing the manner in which my improvedremovable or detachable support serves to maintain the non-conductingcovholes made in the ends of the band. employ a suitable number ofvertical metal ering in proper position between the flanges of the pansection, the covering in this instance being but partially shown. Fig. 3is a vertical sectional elevation of the preceding figure. Fig. 4 is anenlarged view in de tail representing the manner of securing theencircling bands or hoops for the pan in place, and also betterillustrating the form of vertical support for the hoop, as well as themanner in which the adjacent ends of the encircling band or hoop arefastened or joined together. Fig. 5 is a View in detail showing themanner in which the non-conducting covering is secured to the encirclingband or hoop; as well also as the manner in which the outer covering ofcanvas is attached to the felt or non-conducting material.

In carryingmy invention into effect I employ for the section of vacuumpan an encircling bandor hoop which surrounds the section immediatelybeneath the upper flange of said section, the ends of the said band orhoop being securelyjoined together by means of wires or loops passedthrough openings or I also strips the lower ends ofwhich rest upon thelower flange of the section of vacuum pan, and the upper end of saidvertical metal strip is so shaped or formed'as to receive the encircling band or hoop in such manner as to firmly maintain or hold the saidband or hoop up into position beneath the upper flange of the pansection. The felt or non-conducting covering being attached at its upperedge to the encircling band or hoop by means of wire stitching it isobvious that such felt or nonconducting covering will be held snugly inposition around the pan. It should be understood that the vertical metalsupporting strips for the encircling band as well as the band itself liebeneath the felt or covering and rest against the copper body of thevacuum pan, thereby rendering the parts unexposed and furnishing to thepan a neatly covered appearance. The felt or non-cond noting coveringitself is preferably made up of a number of different sections so as toenable any part thereof to be raised or taken out when required, and itwill be observed that'the meeting edges of the said sections are firmlydrawn Vacuum pan as it appears when covered in the manner hereinexplained; a representing the separate sections or blocks ofnon-conducting material; and 1) representing the lacing by which thesaid blocks or sections'of material are firmly joined together.

B represents one of the sections of which the vacuum pan is composed,the same having a continuous flange c on both its upper and lower edges.

0 indicates the metal hoop or band which surrounds the section of panimmediately beneath the upper flange thereof, the meeting ends of saidhoop or band being formed or provided with holes or openings 01, throughwhich openings a wire fastening D is passed for securing the ends of thehoop or band together. The said hoop or band rests in the space formedby slitting the upper end of the vertical supporting strips E so as toform tonguesfon the opposite sides of the band, substantially as shown.The said vertical supporting stripsE may be diiferently formed at theirupper ends, and in fact the band may be secured thereto in any suitablemanner, but the manner of slitting the strips at the upper end and thenbending the separate tongue formed thereby slightly outward has beenfound the most convenient in practice, since it facilitates the readyplacing of the parts in position as well as the separation or removalthereof when desired. As shown in the drawings the felt G is secured tothe encircling band or hoop by means of wirestitching g, while the outercovering or canvas is secured to the felt by means of small rivetsipassing through from one side and fastened on the other side by means ofsmall hooks or loops j.

It is thought from the foregoing description that the nature and objectsof my invention will be fully understood, and it will of course beobvious that immaterial changes could be made in the general form of.parts shown and still be within the scope intended. I do not thereforewish to limit myself to precise details since I might Wish to resort toseveral changes in the mannerof joining and arranging the devices whichserve as the support for the covering. It will be seen that the coveringwill be held in place evenly and compactly, and that the same can bereadily removed either in sections or in entirety whenever desired.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A support for the non-conducting covers of vacuum pans and the like,consisting of a removable encircling band or hoop and a removablesupport for the said band or hoop, substantially as described.

2. A support for the non-conducting coverings of vacuum pans and thelike, consisting of an e'ncircl'inglband or hoop and a vertical supportinto which said band or hoop is remova-bly received, substantially asdescribed.

3. A support for the non-conducting coverings of vacuum pans and thelike, the same consisting of a removable encircling band or hoop unitedat its ends by means of a wire or similar fastening, and a removablevertical support for said band or hoop, substantially as described.

t. A support for the non-conducting coverings of vacuum pans and thelike, thesame consisting of an encircling band or hoop, and a verticalsupport for said band or hoop having its upper end slit and bentoutwardly so as to form a space into which the band or .hoop isreceived, substantially as described.

5. A support for the non-conducting coverings of vacuum pans and thelike, the same consisting of a band or hoop to which the covering isattached, and a vertical support for the band, the said support beingprovided at its upper end with means for receiving and holding saidband, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS WILLIAMS.
